Hi Gwen,
my hubbie sounds like your's - super healthy, never smoked, etc.
His cancer was at the bottom of his throat, above the espoh, so they put a g-tube in for feeding during the treatment- by about the 3rd week he could not swallow anything except liquids. I think the cancer location impacts ability to eat or not - at least this is what his team of docs told us in justification of placing him with a g-tube.
He starting eatting solids about 4 wks after treatment ended and was back to a full diet 6 mo out of treatment - fast forward a year, and the only thing he can't really eat is spicy foods. if you met him on the street, you would never know what he's been through -
In my experience as a caregiver these were the most critical elements to a successful, non-stop treatment:
lots of liquids - almost 2500 cals daily of liquid ensure / nutrin - I never let up on this, not even for a day
lots of water -
lots of glutimine - about 30 mg a day > important protector of cell lining in mouth and muscle - my hubbie lots a lot of muscle during treatment, but put it all back on once he started going to the gym again - his body looks better post treatment!
pain medication - my hubbie was resistant at first - at about wk 4 he started meds for pain - and continued with it until he was about 2 wks out of treatment. I wished we would have gotten ahead of the pain instead of trying to control it after the fact > fiber and stool softners to avoid the unpleasent complications of pain medication
Ibprofrin - (sp) to reduce swelling of throat / pain - just make sure he's getting lots of liquid for liver
following the anti - nausea medication directions before each chemo treatment religiously.
swallow, swallow, swallow - even at the end of treatment, he would swallow at least a glass of water through out the day
dental visits - he gets his teeth cleaned every 6 -8 weeks and uses a special floride tooth paste
food wise - same as you - lots a eggs, foods with sauce
Best of luck and health, Julie
